Beyond this, to be clear, if he goes, it isn't because he didn't succeed on all fronts, like the top clubs tend to aim for.
It's because he didn't succeed in the league, specifically. He could win a cup treble but still be under pressure for finishing 17th - conversely, he could finish 2nd, win absolutely nothing, and be lauded for doing so. That's the message sacking him sends.
As we've discussed, this will not produce the mentality of a top club. All that does is create a mentality of safety-first - finish 4th, win nothing, and keep your job. Take a risk to win a trophy, and lose it.
We mock Wenger-era Arsenal for having this mentality, but sack Ange and this is exactly what we aspire to be, too.
